Radiographic Quality Quiz

When assessing radiographs, which of the following is NOT a factor to consider for ensuring quality?

• Identification

• Correct collimation

• Color of the radiograph

• Absence of artefacts

What does correct projection in a radiograph ensure?

• It ensures the radiograph is free from artefacts.

• It ensures the radiograph has the correct color.

• It ensures the radiograph covers the correct area.

• It ensures the radiograph has the correct positioning.

Artefacts on a radiograph are:

• Always indicative of pathology.

• Things that look real but are caused by factors outside the body.

• Unimportant for the assessment of the radiograph.

• Only caused by poor processing.

What is essential to determine if an X-ray image has adequate contrast?

• The color range of the image

• The range of grey tones and the ability to distinguish all tissue types expected for the body area

• The brightness of the image

• The size of the image

What does density refer to in the context of an X-ray film?

• The weight of the film

• The blackness of the film

• The thickness of the film

• The transparency of the film

What happens if an X-ray film is not black enough?

• It is considered diagnostic

• It is too dark to see a clear image

• It is not considered diagnostic

• The computer cannot compensate for underexposure

What is likely to happen if an X-ray film is too dark?

• You will see a clearer image

• It is considered diagnostic

• You will NOT see a clear image

• The computer will compensate by applying filters

What does resolution refer to in the context of film quality?

• The color contrast of the film

• The size of the film

• The sharpness of the film

• The age of the film

Why is adequate resolution important in diagnostic films?

• It ensures the film is of the correct size

• It prevents pixelation

• It allows for better color representation

• It prevents missing important details due to blurriness

What is a characteristic of an overexposed X-ray film?

• Causes decrease in opacity (whiteness) of the image

• Causes more blackening of the film

• Often just looks blurred with digital

• Can increase exposure by increasing mAs and/or by increasing kV
